DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

It should be noted that a terminal involved in the embodiments of the present invention may be a touchscreen terminal, which includes but is not limited to a mobile phone, a tablet personal computer (PAD), a personal digital assistant (Personal Digital Assistant, PDA for short), a wireless handheld device, a wireless netbook, a portable computer, an MP3 player, an MP4 player, and the like.

FIG. 2 is a flowchart of an application display method according to an embodiment of the present invention. As shown in FIG. 2, the method in this embodiment may include the following steps:

S101. Acquire a first flicking gesture, where a start position of the first flicking gesture is located in a first preset operating area.

In this embodiment, a user of a terminal may start the first flicking gesture from a first preset operating area on a touchscreen, where the touchscreen is a touchscreen of the terminal and the terminal may acquire the first flicking gesture of the user. Specifically, the user may start an operation of a first gesture from the first preset operating area on the touchscreen. When determining that the first gesture performed by the user on the touchscreen is a flicking gesture, the terminal may acquire coordinates of a start position of the flicking gesture. When determining that the coordinates of the start position are located in the first preset operating area of the touchscreen, the terminal may use the flicking gesture as the first flicking gesture and perform S102.

Optionally, the first preset operating area may be a bottom display area on the touchscreen of the terminal, a top area on the touchscreen of the terminal, a left-side area on the touchscreen of the terminal, a right-side area on the touchscreen of the terminal, or a virtual navigation bar area on the touchscreen of the terminal.

Optionally, the first preset operating area may be rectangular, or the first preset operating area may be circular.

S102. When a terminal detects that the first flicking gesture is a first preset flicking gesture, display an application that is in a first state, where the first state includes at least one of the following states: a state of running in the foreground, a state of running in the background, and a state of being buffered in the background.

Specifically, after acquiring the first flicking gesture, the terminal determines an operation track corresponding to the first flicking gesture, where the operation track is a track formed by acting points of an operation, corresponding to information about the first flicking gesture, on the output device. A start position of the operation track is located in the first preset operating area of the terminal. Optionally, that a terminal detects that the first flicking gesture is a first preset flicking gesture is specifically as follows: When a distance of the operation track, corresponding to the first flicking gesture, in the first preset operating area is greater than or equal to a preset threshold, the terminal determines that the first flicking gesture is the first preset flicking gesture. Optionally, that a terminal detects that the first flicking gesture is a first preset flicking gesture is specifically as follows: The terminal determines that the first flicking gesture is the first preset flicking gesture when an angle between a landscape orientation of the output device of the terminal and a line formed by a start point of an operation track and an end point of the operation track is less than or equal to a first threshold, where the operation track is formed in the first preset operating area by the first preset flicking gesture; or when an angle between a portrait orientation of the output device of the terminal and a line formed by a start point of an operation track and an end point of the operation track is less than or equal to a first threshold, where the operation track is formed in the first preset operating area by the first preset flicking gesture. The distance threshold and the angle threshold may be specific values, or may be value ranges. The terminal may also determine, according to the distance and the angle of the operation track, that the first flicking gesture is the first preset flicking gesture.

In this embodiment, when determining that a first flicking gesture is a first preset flicking gesture, a terminal may learn that a user of the terminal requests to acquire an application that is in a first state, where the first state includes at least one of the following states: a state of running in the foreground, a state of running in the background, and a state of being buffered in the background. Then, the application that is in the first state may include at least one of the following applications: an application running in the foreground, an application running in the background, and an application buffered in the background. The application that is in the state of running in the foreground is an application that is running on a current interface. The application that is in the state of running in the background is an application that is not running on the current interface but is not closed. The application that is in the state of being buffered in the background is an application that is not running on the current interface and is closed, but data required for running the application is still buffered in a memory of a terminal device. The application that is in the first state is an application that is recently used by the user of the terminal. Then, the terminal may acquire the application that is in the first state (including a identifier of the application) and display, on the touchscreen, the application that is in the first state. For example, the terminal may display, on the entire touchscreen, the application that is in the first state, or display, in a preset area of the touchscreen, the application that is in the first state. A feasible implementation manner of displaying the application that is in the first state may be generating a list for the terminal, where the list includes the application that is in the first state (for example, the identifier of the application), which is not limited in this embodiment of the present invention. In this case, the user may perform application switching according to the application that is in the first state. In this embodiment of the present invention, the recently used application is displayed to the user according to the flicking gesture of the user, without a need to dispose a dedicated button.

Optionally, that the terminal displays an application that is in a first state may include: The terminal displays, according to preset order, the application that is in the first state, where the preset order may be a descending order of frequency of using an application by the user within a preset time, an ascending order of a difference between a time at which the user uses an application and a current time, or the like.

In this embodiment, a terminal acquires a first flicking gesture, where a start position of the first flicking gesture is located in a first preset operating area of the terminal, and when it is detected that the first flicking gesture is a first preset flicking gesture, the terminal displays an application that is in a first state. Therefore, a recently used application can be displayed to a user according to a gesture of the user, without a need to dispose a dedicated button, thereby improving operation and control efficiency.

Further, that the terminal displays an application that is in a first state includes: The terminal displays, in the preset area, the identifier of the application that is in the first state, where the preset area may be an area that is the same as the first preset operating area. In this embodiment, the terminal may add a window in the preset area so as to display the identifier of the application that is in the first state. For example, a list is generated in the preset area, where the list includes an icon or a name of the application that is in the first state. In this embodiment, the terminal may display, in the preset area in the current application interface of the touchscreen, the application that is in the first state, and it is not required to switch an interface when displaying the application that is in the first state. Therefore, the user may switch an application quickly and intuitively in a case in which no area of an application interface is blocked, thereby enhancing user experience.

Optionally, the preset area may be: a bottom display area on the touchscreen of the terminal, a top display area on the touchscreen of the terminal, a left-side display area on the touchscreen of the terminal, a right-side display area on the touchscreen of the terminal, or a virtual navigation bar area on the touchscreen of the terminal.

Optionally, the first preset flicking gesture is a leftward flicking gesture, a rightward flicking gesture, an upward flicking gesture, or a downward flicking gesture.

In a feasible implementation manner, for a terminal having a virtual navigation bar, the user may perform a leftward flicking gesture on the virtual navigation bar on the touchscreen of the terminal, as shown in FIG. 3. The virtual navigation bar shown in FIG. 3 is located in the bottom display area of the touchscreen. When the terminal detects that the user performs a leftward flicking gesture on the virtual navigation bar, the terminal may display, in the virtual navigation bar by adding a window, the identifier of the application that is in the first state, as shown in FIG. 4.

In a second feasible implementation manner, for a terminal having a physical button, the user may perform an upward flicking gesture in the bottom display area on the touchscreen of the terminal, as shown in FIG. 5. The first preset operating area shown in FIG. 3 is located in the bottom display area of the touchscreen. When the terminal detects that the user performs an upward flicking gesture on the bottom display area, the terminal may display, in the bottom display area by adding a window, the identifier of the application that is in the first state, as shown in FIG. 6. In this implementation manner, the terminal displays, only in the bottom display area, the application recently used by the user, so as to switch an application quickly in a case in which no area of a user application interface is blocked. It should be noted that, this embodiment of the present invention is not limited to the foregoing two feasible implementation manners.

In the application display method provided in this embodiment of the present invention, after the application that is in the first state is displayed, further, based on the method embodiment shown in FIG. 1, the method in this embodiment further includes: acquiring an instruction entered by a user; and displaying, on a current interface according to the instruction, an application interface of an application that is triggered by the instruction, where the application is any application of the application that is in the first state. Specifically, the user may enter the instruction. For example, the user may tap any application (for example, a identifier of the application) of the application that is in the first state and displayed on the touchscreen of the terminal, that is, the user enters a user instruction, where the instruction is used to trigger the application tapped by the user. Therefore, the terminal may acquire the instruction entered by the user and learn that the user requires the terminal to display the application triggered by the instruction; for example, the user needs to switch to the application triggered by the instruction. Further, the terminal may display, on the current interface, the application triggered by the instruction, thereby implementing quick switching between applications.

FIG. 7 is a flowchart of an application display method according to an embodiment of the present invention. As shown in FIG. 7, based on the method embodiment shown in FIG. 1, further, the method in this embodiment may further include the following steps:

S201. Acquire a second flicking gesture, where a start position of the second flicking gesture is located in the first preset operating area.

In this embodiment, after the terminal displays the application that is in the first state, the user of the terminal may start the second flicking gesture from the first preset operating area on the touchscreen. Then, the terminal may acquire the second flicking gesture of the user. Specifically, when determining that a gesture performed by the user on the touchscreen is a flicking gesture, an endpoint terminal may acquire coordinates of a start position of the flicking gesture. When determining that the coordinates of the start position are located in the first preset operating area of the touchscreen, the terminal may use the flicking gesture as the second flicking gesture and perform S202.

S202. When the terminal detects that the second flicking gesture is a second preset flicking gesture, hide the identifier of the application that is in the first state.

Optionally, the second preset flicking gesture may be a flicking gesture that is the same as the foregoing first preset flicking gesture. When the terminal detects that the second flicking gesture is the second preset flicking gesture, if the terminal displays only a part of applications that are in the first state but does not display another part of applications, the terminal continues to display the another part of applications that are in the first state; if the terminal already displays all applications that are in the first state to the user, the terminal may hide displayed identifiers of the applications that are in the first state. For example, a window for displaying an application that is in a first state may be closed. If the current interface is an application interface of a running application, the identifier that is previously displayed and is of the application that is in the first state may be hidden, but the application interface of the running application displayed on the current interface may still be retained.

Optionally, the second preset flicking gesture may be a flicking gesture inverse to the foregoing first preset flicking gesture. For example, if the first preset flicking gesture is a leftward flicking gesture, the second preset flicking gesture is a rightward flicking gesture; if the first preset flicking gesture is a rightward flicking gesture, the second preset flicking gesture is a leftward flicking gesture; if the first preset flicking gesture is an upward flicking gesture, the second preset flicking gesture is a downward flicking gesture; if the first preset flicking gesture is a downward flicking gesture, the second preset flicking gesture is an upward flicking gesture. When the terminal detects that the second flicking gesture is the second preset flicking gesture, it indicates that the user no longer requests to acquire the application that is in the first state. Then, the terminal may hide the displayed identifier of the application that is in the first state. For example, a window for displaying the application that is in the first state may be closed.

In this embodiment, further, a terminal acquires a second flicking gesture, where a start position of the second flicking gesture is located in a first preset operating area of the terminal, and when it is detected that the second flicking gesture is a second preset flicking gesture, hides a identifier of an application that is in a first state. Therefore, the identifier that is displayed on the terminal and is of the application that is in the first state may be hidden according to a gesture of a user.

FIG. 8 is a flowchart of an application display method according to an embodiment of the present invention. As shown in FIG. 8, further, the method in this embodiment may include the following steps:

S301. A terminal acquires a first flicking gesture, where a start position of the first flicking gesture is located in a first preset operating area of the terminal.

A specific implementation process of S301 in this embodiment is similar to the specific implementation process of S101 in method embodiment 1 of the present invention. For details, refer to related description of the foregoing method embodiment of the present invention, and details are not described herein again.

S302. When the terminal detects that the first flicking gesture is a first preset flicking gesture, the terminal displays identifiers of a first part of applications that are in a first state.

In this embodiment, if there are a relatively large quantity of applications that are in the first state, when a display area of a touchscreen of the terminal cannot display, in a display interface, all applications that are in the first state, a part of applications that are in the first state may be displayed. For example, a first part of applications that are in the first state may be displayed. The remaining applications that are in the first state may be displayed when a user performs a next first preset flicking gesture. In this embodiment, after S302 is performed, S303 may further be performed.

Optionally, the terminal displays, in a preset area of the touchscreen, the identifiers of the first part of applications that are in the first state.

S303. The terminal acquires a second flicking gesture, where a start position of the second flicking gesture is located in the first preset operating area.

A specific implementation process of S303 in this embodiment is similar to the specific implementation process of S201 in method embodiment 2 of the present invention. For details, refer to related description of the foregoing method embodiment of the present invention, and details are not described herein again.

S304. The terminal detects whether the second flicking gesture is the first preset flicking gesture. If yes, perform the step S305; if not, perform the step S306.

In this embodiment, the terminal detects whether the second flicking gesture is the first preset flicking gesture; if it is detected that the second flicking gesture is the first preset flicking gesture, performs S305, or if it is detected that the second flicking gesture is not the first preset flicking gesture, performs S306.

S305. The terminal displays, on a touchscreen, identifiers of a second part of applications that are in the first state.

In this embodiment, when it is detected that the second flicking gesture is the first preset flicking gesture, the terminal may learn that the user of the terminal still requests to acquire the application that is in the first state. Because the identifiers of the first part of applications that are in the first state are already displayed previously, identifiers of the remaining applications that are in the first state may be displayed on the touchscreen at this time. For example, identifiers of a second part of applications that are in the first state may be displayed on the touchscreen.

Optionally, the terminal displays, in the preset area of the touchscreen, the identifiers of the second part of applications that are in the first state.

S306. When the terminal detects that the second flicking gesture is a second preset flicking gesture, the terminal hides the identifiers of the first part of applications that are in the first state.

In this embodiment, after the terminal detects that the second flicking gesture is not the first preset flicking gesture, when the terminal detects that the second flicking gesture is the second preset flicking gesture, it indicates that the user no longer requests to acquire the application that is in the first state. Then, the identifiers that are displayed on the touchscreen and are of the first part of applications that are in the first state may be hidden. For example, a window for displaying the application that is in the first state may be closed.

In this embodiment, a recently used application can be displayed to a user according to a gesture of the user, without a need to dispose a dedicated button. Further, the application that is recently used by the user may further be displayed in a preset area (for example, a bottom area) of a touchscreen, so as to switch an application quickly in a case in which no area of a user application interface is blocked, thereby enhancing user experience.

Optionally, in the foregoing embodiments of the present invention, an entire operation track of the first preset flicking gesture is located in the first preset operating area. Optionally, an entire operation track of the second preset flicking gesture is located in the first preset operating area.

FIG. 10 is a schematic structural diagram of a terminal according to an embodiment of the present invention. In this embodiment of the present invention, the terminal may be a computer system in a handheld form, such as a smartphone, a tablet personal computer (Tablet Personal Computer), a personal digital assistant (personal digital assistant, PDA for short), a mobile Internet device (Mobile Internet Device, MID for short), a wearable device (Wearable Device), or the like. Persons killed in the art may understand that the structure of the terminal device shown in FIG. 10 does not constitute a limitation on the terminal device, where the terminal device may include parts more or less than those shown in the figure, or a combination of some parts, or different part arrangements. The following describes integral parts of the terminal device in detail with reference to FIG. 10.

An input device 22 is configured to implement interaction between a user and an electronic device and/or input of information into the electronic device. For example, the input device 22 may receive digit or character information that is entered by the user, so as to generate a signal input related to user settings or function control. In a specific implementation manner of the present invention, the input device 22 may be a touch panel, or may be another human-machine interaction interface, such as a physical input button or a microphone; or may be another apparatus for acquiring external information, such as a camera. The touch panel, also referred to as a touchscreen or a touchscreen, may collect an operation action of touching the touch panel or approaching the touch panel, for example, an operation action performed by the user on the touch panel or at a position close to the touch panel by using any proper object or accessory such as a finger or a stylus, and a corresponding connecting apparatus is driven according to a preset program. Optionally, the touch panel may include two parts: a touch detection apparatus and a touch controller. The touch detection apparatus detects a touch operation of the user, converts the detected touch operation into an electrical signal, and transmits the electrical signal to the touch controller; the touch controller receives the electrical signal from the touch detection apparatus, converts the electrical signal into touch point coordinates, and then transmits the touch point coordinates to a processor 23. The touch controller may further receive and execute a command sent from the processor 23. In addition, the touch panel may be implemented by using multiple types, such as a resistive type, a capacitive type, an infrared (Infrared) ray, and a surface acoustic wave. In another implementation manner of the present invention, the physical input button used by the input device 24 may include but is not limited to one or more of a physical keyboard, a functional button (such as a volume control button or a power button), a trackball, a mouse, an operating lever, or the like. An input device in a form of a microphone may collect voice that is input by the user or an environment, and convert the voice into a command that is in a form of an electric signal and can be executed by the processor 23.
